I'm not trying to hate on your call for all crossfire members, but I would venture to guess you are the 15th or so person to mention this. You have been around here a pretty long time and know about the various scams that have covered this exact topic. I'm not saying you are one of those people, you have been a great forum member in your time. You just have to understand the lack of enthusiasm for this mod if for nothing else because of its history of failure and scandal. And 4k for a standalone, injectors and a fuel pump is a lot of money, injectors and a fuel pump should cost about $600 dollars which means there is over 3k left for a standalone and there are plenty of really good high quality stand alones for half that amount. I used to run a wolf 3d standalone ecu on my rx7 and paid $600 dollars for it. Those types of parts should really be left on the shelf for people to pick up themselves unless the kit is going to come plug and play with proper tuning for different fuel types, i.e. 91, 92, 93 and 94.

I really do wish you and the above poster the best of luck in this endeavor. There are additional aftermarket parts to those you have mentioned, like larger air boxes, cams and pulleys.
